It must be said
• Very atypical request• Amounting to a PH Professionals dream in
its far-sightedness• Not the usual Health Sx or systems Mx
request or even clinical request• But directed at the primary end of the
prevention hierarchy, and • Intrinsically inter-sectoral in approach

The six original proposals
PROPOSAL 1:To produce estimates of the Provincial burden of disease for the Western Cape , utilizing both morbidity and mortality data, both at a provincial level and at the level of the 6 districts, for the year 2005.
PROPOSAL 2: To optimally design a rapid mortality surveillance system for districts with expert public health support from the MRC and UCT Public Health, and assist with its institutionalization and rollout.
PROPOSAL 3: To ascertain the available information on the incidence and prevalence of mental health morbidity both nationally and in the Western Cape, in order to derive estimates of the BoD in DALYs due to mental illness in the Province and explore the scope for conducting morbidity surveillance.
PROPOSAL 4: To ascertain the availability of current facility-based morbidity data within Western Cape health information systems, and its potential utility for input to provincial Burden of Disease estimation.
PROPOSAL 5: To produce an inventory of public (and private/NGO) sector interventive responses aimed at reducing BoD risk factors
PROPOSAL 6: To compare the inventory of interventive responses with a master list of interventions, to identify gaps and to evaluate existing interventions within the context of a surveillance system.

1. Major Infectious diseases Unsafe sex
2. Injury Alcohol abuse
3. Mental disorders Early Childhood Development
3. Cardiovascular disease Obesity and Exercise

5 Expert Groups
• Structure and function– each group with specific champion– Authors identified– Multi stakeholder expert group assembled–including
many members of PRG– examined evidence for intervention effectiveness
(where this existed or was possible) or promise (where more complex causally).
– Peer review (incl. international review) where possible given time constraints

Acute Respiratory Infections
Malnutrition

The 7 Volumes
Constitute a rich source of outputs with useful information about interventions against the major risk factors for the top 5 BoD components for which there is either– Evidence– Or which are agreed to be promising
20
Fidelity to mandate
• Maintained faithfulness of mandate to look upstream in terms of – The conceptual model focussing on societal and
structural risk factors and levels of intervention – and beyond the health department to other sectors
and relevant government departments
• While retaining focus on “downstream” health sector based interventions with recursive preventive effects at the primary level eg ARVs, Mental Health Services

Main Points: 1. Surveillance is crucial
• Whatever we do with interventions into the future we need to know where we are at any one time, and what the impact measurable at the population level could be.
• So we need improved and institutionalised mortality surveillance systems sensitive to rapid change at the most disaggregated level
23
2. Upstream risks and upstream interventions for all risks
are critical for reduction of BoD
• Have highlighted the role of behavioural factors (alcohol, road use, sexual and health-seeking) in contributing to the BoD
• And how these link to even more upstream infrastructural risks of material and social deprivation
• And how upstream interventions have multiple direct and indirect impacts on all risks
24
Used global and local evidence
• To provide highlights of upstream
interventions that have been:– shown to be effective– or are considered by consensus to be promising
25
Value of the output
• Study has not broken entirely new ground• Overlap with WCPPoA 07/08 – provincial
strategic objectives• Our recommended interventions can provide
detail and more concrete proposals for the achievement of these strategic policy objectives
• Provides a menu of interventions for policy makers – and a guide to feasibility and practicability
26
Value of the output (2)
• Our recommendations can help assessment of current, consideration of new, and dropping of existing interventions that have been shown not to work.
• The devil is in the detail – some interventions are nominally present but
not implementable any time soon and – others are inadequately targeted to high risk
groups who could benefit most
27
Tasks ahead for 2007/8
28
Principal tasks as seen by the project team
1. Institutionalisation of mortality surveillance should continue
2. Intersectoral engagement with other non-health government departments on upstream interventions to mitigate risk, involving:
a. Identification of optimal intersectoral structures and vehicles for reducing the BoD
b. Making specific Public Health contributions to this work including assistance with design of intervention implementation and monitoring systems and data analysis and interpretation for evaluating these interventions over time
29
Structure of Symposium
• Presentations in some detail
• Lots of time for input from the floor
