uly 2014 marks an important milestone in Tan Tock Seng Hospital (TTSH)’s history. 170 years ago, TTSH became the first

Chinese Pauper’s Hospital to care for the ‘diseased of all nations’. Today, its legacy as a people’s hospital continues to be rooted in our vision, mission and values. This is a shared achievement with our General Practitioners (GP) partners and patients who have witnessed the transformation of the hospital amidst changes and challenges.

In this issue of GP BUZZ, we take you through memory lane, with reviews of TTSH’s key achievements in a special commemorative segment. In conjunction with our hospital’s 170th birthday, we would also like to seek your generous contribution of TTSH heritage memorabilia.

TTSH’s Community Right-Siting Programme (CRiSP) and the newly launched Pioneer Generation Package by the Ministry of Health are two initiatives that provide more affordable healthcare to the community. GP BUZZ brings you the updates on CRiSP and the Pioneer Generation Package and review how they benefit our patients.

In this edition, we cast the spotlight on thyroid nodules, which are commonly detected in the primary

care setting. GP BUZZ walks you through the diagnostic process and treatment options for prompt investigation and management of your patients. In another article, GP BUZZ explores the mechanics of robot-assisted thoracic surgery and its benefits in the treatment of early stage lung cancer.

The manual by National Healthcare Group Eye Institute (NHGEI), titled ‘Fundus Photograph Interpretation for Primary Eye Care Practitioners', is officially launched in this magazine, through a feature article.

GP BUZZ also brings you the Chronic Disease Self-Management Programme (CDSMP) and explains how better communication skills and structured self-management techniques can help chronic disease patients enhance their quality of life and self-efficacy.

In conjunction with World Heart Day on 29 September 2014, GP BUZZ is pleased to share how physical readiness can be determined and physical activities can be prescribed to pump up your heart for a healthier you. Ending on a sweet note, we present a heart-healthy recipe developed by TTSH in the Healthy Recipe section of GP BUZZ.

WON EXCEllENCE IN PUBlIC SERVICE AWARD, BEST PRACTICE AWARD 2014

Tan Tock Seng Hospital (TTSH)’s ward revamp project - the ‘Ward of the Future’ (WOF) bagged the Excellence in Public Service Award, Best Practice Award for Organisation

Development.

This award aims to recognise organisations that demonstrate the use of organisational development principles, including taking a systems view, understanding of behavioural processes and emphasising on humanistic behaviour, while coming up with quality solutions to achieve success.

TTSH WOF was lauded for its success at strategically leveraging on infrastructure to enable work redesign and transform care delivery. Besides structural improvements in the TTSH wards, work processes were reviewed to enhance care delivery as well as to increase patient and staff satisfaction.

The refurbished wards now include cubicle-based work stations and a decentralised supplies cabinet. This new layout helps to reduce unnecessary foot traffic within wards, which in turn helps nurses to make better use of time for patient care. Other new ward features include anti-slip floors, en suite toilets, Acute Care areas and the End of Life room, to meet the different needs of patients.

‘WARD OF THE FUTURE’

CRYOABlATION - NEW PROCEDURE IN KIDNEY CANCER TREATMENT

Tan Tock Seng Hospital (TTSH) rolled out a new procedure that destroys tumours on the kidney, known as

Cryoablation.

This new procedure is conducted by inserting a probe into the tumour and rapidly cooling the probe to minus zero temperature. The temperature of the frozen water in the cancer cells is later raised, causing the tumour to expand rapidly and thus destroying them completely. The procedure is conducted using a Computed Tomography (CT) scan and it lowers the risks made to the other organs around the kidney.

Cryoablation is not intended to replace conventional surgery, but it presents itself as an option for patients who cannot undergo surgery, especially elderly patients. To date, TTSH has administered this new technique on six patients, aged 60 to 80 years old.

On 14 May 2014, 12 healthcare professionals from Tan Tock Seng Hospital (TTSH) received the annual Healthcare Humanity Awards (HHA) from Dr Tony Tan

Keng Yam, President of Singapore and Mr Gan Kim Yong, Minister of Health, at the ceremony in Biopolis.

This year, a record number of 76 healthcare workers were honoured from across 26 public hospitals, polyclinics, nursing homes and related organisations.

The HHA is a lasting legacy of the Courage Awards, originally presented in 2003 to the healthcare heroes and heroines of the SARS outbreak. It was replaced by the HHA the following year.

As part of the National Healthcare Group’s Regional Health System (RHS) initiatives,

Tan Tock Seng Hospital (TTSH) has seen about 80 patients on its Home Ventilation Respiratory Support Service (HVRSS).

HVRSS aims to help patients with respiratory ventilation problems enjoy a

better quality of life at home. Under this programme, caregivers are also trained to use the respiratory machine and manage the condition of their loved ones.

HVRSS has also helped to cut down extended stays in the hospital and hence free up more resources in the wards.

Tan Tock Seng Hospital (TTSH)’s heritage takes us back 170 years when it was built as a hospital for the poor in the Chinese community. Today, TTSH remains committed to its legacy of compassion, philanthropy and care and its duty as a people’s hospital.

In the past, the hospital witnessed the transformation of healthcare and braved multiple challenges and tough times (e.g. SARS in 2003, H1N1 in 2009). We would not have come this far without the support from GP partners and patients.

In this issue, we take a walk down memory lane, in review of TTSH’s historical milestones and its growth over the years, in service to the community.

1844Tan Tock Seng, a businessman, philanthropist and the first Asian Justice of Peace, donated Spanish $7,000 to build the first hospital for the sick and poor on Pearl’s Hill on 25 July.

GP BUZZ spoke to Adjunct Assistant Professor Chong Yew Lam, Programme Champion of the Community Right-Siting Programme (CRiSP) on this new care initiative by Tan Tock Seng Hospital (TTSH) in the October – December 2013 issue of the magazine.

Here are the updates on the programme and upcoming government initiatives to address the rising healthcare burden of the ageing Singapore population.

CRiSP is a partnership between TTSH and our primary care partners, where stable chronic patients from TTSH Specialist Outpatient

Clinics (SOCs) are being appropriately reviewed and cared for at the primary care environment.

CRiSP aims to integrate TTSH’s existing right-siting programmes such as the Asthma Decant Programme and Heart Failure Programme, with other medical conditions such as benign prostatic hyperplasia of the anxiety, depressive disorder and osteoarthritis of the knee.

COmmUNITY RIGHT-SITING PROGRAmmE (CRiSP)

11

feature

Update on CRiSP PilotSince the launch of CRiSP, 22 General Practitioner (GP) clinics including the two Family Medicine Clinics, have participated in the CRiSP pilot.

TTSH CRiSP works with participating GP partners through a shared-care model, where right-sited patients returning to TTSH SOCs for specialist intervention can be assured of faster SOC subsidised appointments. With Community Health Assist Scheme (CHAS) accredited GP clinics, patients right-sited from TTSH to GPs under CRiSP are also eligible for subsidised SOC appointments beyond the eligible period without going through the polyclinic route again.

Under CRiSP, patients were identified and right-sited to the

community. These patients were found to be in stable condition and had optimised medications, thus making them suitable candidates for right-siting.

What’s Next?In the coming year, CRiSP GP partners will be augmented with National Healthcare Group Diagnostic support, which provides right-sited patients with access to selected subsidised radiology and

laboratory investigations. GP partners can also access the National Electronic Health Record (NEHR) for clinical notes to manage the health outcomes of their patients in the most efficient way possible.

Moving forward, CRiSP is committed to benefit more patients this year and to improve accessibility of care by enlisting the participation of more GP partners in this programme.

THYROID NODULeS: Sorting the Wheat From the Chaff

Thyroid nodules are a common problem in the primary care setting. even though the incidence of malignancy remains low at around 10%, nodules are still a cause of anxiety for patients, especially in cases that are symptomatic or enlarging. Timely referral to the specialist surgical clinic enables the nodules to be investigated and treated promptly.

14

feature

HoW do tHyRoid NodUleS PReSeNt?Thyroid nodule cases are frequently referred to the Head and Neck Surgery clinic, under the General Surgery Department in Tan Tock Seng Hospital (TTSH). It is estimated that up to 60% of the population may harbour thyroid nodules.

While a majority of nodules are small, asymptomatic and never noticed; others may present as a lump in the anterior neck as a first symptom. While painless, the patient may be alarmed by an increasing growth or onset of compressive symptoms such as difficulty in swallowing. Rapid growth of the nodule may cause pain in some cases.

Young and educated patients are among those concerned about the risk of malignancy. Given the prevalence, many patients are also aware of family or friends who have had similar problems or have undergone previous surgery.

MAkiNG tHe RiGHt diAGNoSiSAfter an adequate examination, the workup for thyroid nodules should include an ultrasound and fine-needle biopsy. Blood tests to determine the thyroid function may be done to screen for concomitant hyper- or hypothyroidism.

Since an examination is insufficient to differentiate solid from cystic nodules as well as to screen for other non-palpable nodules or lymph nodes, an ultrasound is recommended. The ultrasound is accurate in picking up features that immediately raise the suspicion of malignancy. This can then be followed by an ultrasound-guided fine-needle biopsy of the nodule(s). Such targeted biopsy increases the yield of cytology by up to 75%.

In our practice at TTSH’s General Surgery Department, a one-stop service is provided such that all these investigations are performed within the clinic upon initial consultation. This serves to greatly allay the patient’s fears and anxieties as the cytology result is often available the next day.

For patients with large cystic nodules, complete aspiration via ultrasound guidance provides immediate relief and assurance. When thyroid malignancy is suspected, further imaging of the neck for invasion or metastasis using Computed Tomography (CT) scan or Magnetic Resonance Imaging (MRI) may be obtained within a short notice. Nowadays, a radionuclide thyroid scan has very limited utility.

WHiCH tReAtMeNt iS SUitAble foR tHe PAtieNt?When the thyroid cytology report is available, patients are counselled based on the National Cancer Institute (Bethesda classification) recommendations. A benign result brings reassurance and relief.

15

feature

The patient may then opt for a conservative approach with regular follow-ups and surveillance ultrasound with the referring primary care physician.

A cytology result that is malignant or suspicious would warrant total thyroidectomy, often performed with nodal dissection. The remaining categories of cytology require further discussions with the patient. Surgery may eventually be necessary to ascertain the histology accurately.

Some patients with large, benign nodules may still opt for surgery

because of fear of a false-negative result, persisting symptoms or for cosmetic reasons.

Traditional open surgery with a cosmetic-centric and minimal-scar approach is the standard recommendation. For patients keen to avoid a neck scar, endoscopic and robotic thyroidectomy are available. Both surgical approaches allow the thyroid to be resected via incisions that are sited away from the neck such as in the chest and axilla.

ROBOT-ASSISTED THORACIC SURGERY

Lung cancer is a leading cause of death from cancer in Singapore. The treatment of

lung cancer depends on a number of factors such as the extent of the cancer (stage) and the patient’s overall health. Surgery is one of the treatment options available to patients and traditionally involves the use of a large cut on the side of the chest. This increases post-operative discomfort and patient requires a longer hospital stay to recover from the surgery.

Over the years, Video-Assisted Thoracic Surgery (VATS), a minimal-access approach that allows

surgeons to perform lung cancer surgery through three to four small incisions was introduced. However, VATS demands skills that are very different from the hand motions used in traditional open surgery, and hence requires longer training times to master such procedures.

Robot-assisted thoracic surgery is an extension of VATS and this technology is able to replicate the surgeon’s hand movements precisely. Consequently, the training time required to master the movements using the robot is much shorter, resulting in its widespread acceptance in the USA and Europe.

HoW doeS RobotiC SURGeRy WoRk?The surgical robot was originally developed by the US military, to allow complex surgery to be performed on a wounded soldier by a surgeon on a console at a hospital, removed from the battlefield.

The robot provides enhanced vision and control and is made up of several components, which includes an ergonomically-designed console, four interactive robotic arms and a three-dimensional (3D), high-definition vision system. The four interactive robot arms are introduced into the patient’s chest

Surgery is the treatment of choice in early-stage lung cancer and has traditionally been performed through a large cut on the side of the chest. This results in increased pain and a longer hospital stay for patients.

Robot-assisted thoracic surgery is a minimal-access approach that allows surgeons to perform operations remotely, using robotic arms inserted through several small incisions. With this technology available at Tan Tock Seng Hospital, our patients are able to experience less pain and a shorter hospital stay.

using small incisions, while the surgeon sits at the console and uses finger, eye and foot controls to manipulate the arms of the robot.

Robot-ASSiSted SURGeRy foR lUNG CANCeRIn robotic lung cancer surgery, surgeons operate through small incisions in the chest to remove the cancer and a certain amount of surrounding healthy tissue from the affected lobe of the lung. The right lung consists of three lobes, while the left lung is made up of two.

At Tan Tock Seng Hospital (TTSH), several different types of lung cancer operations are performed, depending on the size and the location of the tumour.

1. Robot-Assisted Wedge Resection

With this procedure, the surgeon removes a small wedge-shaped portion of the lung, which includes the cancer and some healthy tissue surrounding the tumour.

2. Robot-Assisted Sub-lobar Resection With this procedure, the

surgeon removes a segment of the lobe containing the cancer, with some normal surrounding lung tissue.

3. Robot-Assisted lobectomyWith this procedure, the surgeon removes the entire lobe containing the cancer, for example, the left upper lobe.

18

feature

Regardless of the type of procedure performed, surgical removal of the lymph nodes surrounding the lung is also performed using the robot. This allows the surgeon to determine if the cancer has progressed beyond the lungs.

AdVANtAGeS of Robot-ASSiSted lUNG CANCeR SURGeRyRobot-assisted lung cancer surgery is performed through a series of small incisions, which results in faster recovery and significantly less post-operative discomfort and scarring, as compared to traditional open lung cancer surgery that requires a large incision.

Since the introduction of robotic lung cancer surgery at TTSH in 2012, we have seen an improvement in our patients’ post-operative recovery as well as reduced hospital stays (three to four days).

The other advantage of using robotic surgery in lung cancer includes the surgical robot’s high definition, 3D camera, which provides a superior view of the tissues being operated on. The robot is also able to translate the surgeon’s hand, wrist and finger movements into real-time movements of the surgical instruments inside the patient. This allows for exceptional precision, which is ideal for resecting lung tissues and removing lymph nodes within the chest.

WoRkiNG AS A teAM iN Robot-ASSiSted lUNG CANCeR SURGeRyAt TTSH, we offer a team-based approach to robot-assisted thoracic surgery. Surgeons are accompanied by a team of trained nurses and supporting healthcare staff to ensure that every patient receives quality and personalised care.

fundus Photograph interpretation for Primary eye Care Professionals

In recent years, greater emphasis has been placed on the early detection of diseases

at the primary healthcare level. Eye diseases such as diabetic retinopathy, age-related macular degeneration and glaucoma are the leading causes of blindness in Singapore and worldwide. These conditions can be detected with fundus photography – the perennial conservative tool for ophthalmic diagnosis.

Fundus photography has an edge over the direct ophthalmoscope as the latter needs a greater skill to perform and allows only a limited view of the fundus at a time. In addition, with direct ophthalmoscopy, there is no means of keeping a record, other than through manual drawing. On the other hand, fundus photography offers means of capturing wider-view digital images of the fundus.

With newer technology, fundus images can be captured without dilating the pupils, thus eliminating the need for assessing the suitability of dilating the pupils and the risks associated with pupil dilation such as acute angle-closure glaucoma.

20

feature

While the fundus camera can be operated by technicians, the interpretation of images acquired require some knowledge, skills and experience. The doctors in National Healthcare Group (NHG) Eye Institute, together with a senior optometrist, have compiled a user-friendly guidebook on the interpretation of fundus photography for use by primary care professionals. This is believed to be first of its kind locally.

One of the challenges in the interpretation of fundus photography is the wide variety of normal fundi seen in our local population. The appearance of fundus may be affected by age, race, degree of myopia and other factors. We have compiled a wide range of normal fundi and provided guidelines on subtle changes to watch out for in diseases such as glaucoma, macular pucker and diabetic maculopathy.

Other highlights of the book include advice on choice of fundus camera, practical tips on its use and possible artifacts. Case studies of real-life scenarios in optometric practice are included as well.

Presently, there is a national effort to provide centralised online reporting of fundus images by trained personnel and optometrists. It is hoped that with this book, more primary eye care professionals will perform fundus photography as part of the eye disease detection and join the fight for blindness prevention.

of morbidity and mortality in Singapore. Ischaemic heart disease, stroke and cancers are among the top five causes of death* in Singapore. Hyperlipidemia, hypertension and diabetes are

among the top four conditions for polyclinic visits**.

Chronic diseases are often long- drawn and treatments are not simply just medications, but involve learning to cope with difficult emotions, symptoms and improving communication with others.

Communication skills for Better engagement and self-Management Are your patients ignorant of their own health conditions? Are your diabetic patients not complying with prescriptions, despite reminders and explanations? Good communication is key in building good doctor-patient relationships and it lays the vital foundation for patient engagement and compliance. Good partnerships between doctors and patients facilitate shared decision-making.

Empowering our patients with communication skills that enable them to be active and take charge of their health is an important strategy for healthy and happy outcomes. Communication is a two-way process that requires asking, listening, repeating and clarifying by the doctor and patient. Medications not working, medication side-effects, tiredness, anxiety and frustrations are

presented frequently in clinic consults. Patients can be more active in their chronic disease management through better communication.

To do so, they can make the consultation more meaningful by preparing a list of questions before the appointment date and prioritising their concerns on that list. During consultation, patients should use the list of prepared questions, listen and seek clarifications regarding symptoms, diagnosis, laboratory results and medications.

Towards the end of the consult, patients can also learn to repeat what the doctor has explained and even make notes. By repeating what has been said, patients show understanding and this heightens engagement. Doctors work under pressure, so imparting better communication techniques to patients promotes patient self-management and avoids misunderstandings and conflicts.

Goal setting through action planningSeeking good health is everyone’s goal. Public health policies strongly support preventive health. Healthcare providers, Health Promotion Board and the media have been successful in raising awareness of cardiovascular disease, cancers, degenerative disease and their risk factors.

However, helping people to make behavioural changes in lifestyle habits and to effectively manage their diseases still remains a daunting task. Besides better communication, learning to set goals through action planning is another important strategy for active self-management.

feature

In setting any goal, we need to ask ourselves what we really want to do and the emphasis here is on ‘what I want’, not what someone else wants.

The next step involves working out the specifics of ‘how, where and when’ to do it. A self-rating measure of confidence is added on to evaluate the potential success of such a plan. When the plan is carried out, review the outcomes and seek solutions for difficulties or failures. With successive practices, we learn to make better action plans and become more confident in achieving our goals. We can achieve better outcomes in health and disease as well as in other areas of life where we desire to make changes.

Chronic Disease self-Management programme (CDsMp)Tan Tock Seng Hospital (TTSH)’s Chronic Disease Self-Management Programme (CDSMP) is a stepped programme developed by Stanford University that teaches active self-management to enhance the quality of life and self-efficacy. Studies report better symptoms and emotions, greater activity, medication usage, better communication with healthcare providers and reduced utilisation of healthcare services.

Key concepts include goal setting, action planning, problem solving, and the use of self-management tools. Through a series of feedback, brainstorming, discussions and lectures, individuals become empowered in helping themselves and others manage chronic diseases.

CDSMP consists of weekly sessions of about 2½ hours conducted over six weeks. Patients can be referred by family doctors or they can refer themselves to attend the programme. Each workshop is led by two trained facilitators and is conducted at TTSH.

PHYSICAl ACTIVITY FOR THE HEART

Regular physical activity is crucial in preventing and managing lifestyle-related diseases and heart disease. An ideal physical programme should include both aerobic, resistance and lifestyle-related activities to improve endurance and strength training. Physical activity prescription should be tailored according to age, physical fitness and gradual progression for sedentary adults.

According to the Ministry of Health, one third of Singaporean deaths in 2011

and 2012 were due to heart-related conditions. 10% of total hospital admissions in these two years were linked to heart disease and 40% of polyclinics’ attendances were due to risk factors of heart disease (e.g. hyperlipidemia, hypertension and diabetes mellitus). These statistics demonstrate the rising healthcare burden of heart disease in Singapore.

The heart is the engine of the human body; it ensures consistent and continuous delivery of oxygen and nutrients to our body tissues. Optimum heart function is essential to ensure health and vitality. This can be optimised through regular and sufficient doses of physical activity.

Today, there is an increasing trend of reduced physical activity due to mechanisation. Living a sedentary lifestyle has been associated with increased risks of chronic diseases, cancers, obesity, accelerated functional deterioration and lower life expectancy. Strong evidence has supported the risk of developing both heart disease and early death from occupations that are less active.

The 2010 National Health Survey demonstrated that 39.1% did not meet physical activity guidelines for healthy living. Therefore, physical inactivity is an avoidable risk factor for heart disease.

types of physical activityAlthough increasing activity levels have obvious benefits, getting people to participate can be challenging. There are many barriers – on the personal level through external factors and other environmental factors that affect

adherence to regular physical activity. In addition, there is lack of understanding on the types and dosage of physical activity in reaping real health benefits. It is usual to assume that any form of physical activity is considered sufficient for health promotion.

Physical activity is defined as any body movement produced by muscle contractions that result in the burning of calories. In contrast, exercise is a purposeful physical activity programme to ensure gains or maintenance in physical function and fitness (e.g. running, walking, dancing, swimming).

Exercise programmes can be divided into aerobic and resistance physical activities. Aerobic exercises help in improving endurance and fitness, while resistance exercises help in

loading and strengthening both bones and muscles strength. In order to maximise benefits from incidental physical activity, a new modality, which is ‘lifestyle physical activity', was formulated to acknowledge the role of these activities. Local guidelines of physical activity have an inclusive model for various types of physical activity to improve adherence to regular physical activity.

Benefits of physical activityRegular exercise can reduce overall risk of developing heart disease by 50%, possibly through reduction of hardening, narrowing and decreasing the risks of acute blood clot formation in the blood vessels of the heart. Franklin and McCullough 2009 (Table 1) suggested that it could be contributed by improved dilation, compliance or a combination of factors on the blood vessels.

Anti-atherosclerotic (Reduce stiffness of blood vessels)

Anti-thrombotic(Reduce acute blood clot formation)

Anti-ischaemic(Reduce risk of insufficient blood flow)

Anti-arrhythmic(Reduce irregularity of heart rate)

screening and readiness for physical activityBefore prescribing exercise, it is important to screen for red flags for risks of participation in physical activity. Physical activity readiness questionnaire (PAR-Q) is a readily accessible tool to address risks. Further assessment may be required for any “yes” to the questionnaire as well as supervision of exercise intensity and progression. After assessing risks, physical activity prescription is made through the Frequency, Intensity, Type and Time (FITT) principle.

Walking is a great form of exercise through everyday physical activity. It is readily accessible, does not require equipment and has low health risks. Walking intensity can be gradually built up, according to the physical capacity of each individual. Walking is beneficial for all ages to increase mobility and strength, while reducing the risks of disability and chronic diseases.

Table 4 provides a set of recommended walking speeds for males and females of different age groups. Walk at a comfortable pace for a few minutes to warm up before progressing to the ideal speed suitable for your age; maintain the speed for 30 minutes before cooling down to a slower speed. For sedentary adults or individuals with joint pains and injuries, it would be preferable to start at a slower pace in short bouts of 10 minutes before progressing to an ideal duration of 30 minutes.
