DRUG ABUSE IN PAKISTAN
(Subsequently figures were derived separately for each
prov<strong>in</strong>ce, from Census Bullet<strong>in</strong>s 7-10.) This percentage is used
<strong>in</strong> conjunction with the section 1 figure for the toal male population
to provide the number of males <strong>in</strong> the target age-band,
for each locale-group<strong>in</strong>g.
Data structures presented
Percentage of males <strong>in</strong> target age-band
Number of males <strong>in</strong> target population
3. Locale cl<strong>in</strong>ic profiles
Data from the treatment Register Update Study are used to estimate
the number of male hero<strong>in</strong> addicts <strong>in</strong> treatment
Section 3 of the table presents <strong>in</strong>formation collected <strong>in</strong> the
Treatment Register Update component of the National
Assessment. This <strong>in</strong>formation gives the key figures of (i) the
total numbers of <strong>in</strong>patient cases <strong>in</strong> the past year who have
attended the listed specialist (<strong>in</strong>patient) cl<strong>in</strong>ics; and (ii) the
percentage of <strong>in</strong>patient cases who were male hero<strong>in</strong> addicts,
along with other <strong>in</strong>formation on the listed cl<strong>in</strong>ic services.
Comb<strong>in</strong><strong>in</strong>g these figures allows the calculation of the number
of male <strong>in</strong>patient hero<strong>in</strong> addiction cases, although only
<strong>in</strong> 7 of the locale-group<strong>in</strong>gs, s<strong>in</strong>ce the locales <strong>in</strong> Balochistan
other than Quetta had no recorded <strong>in</strong>patient services. So <strong>in</strong>
Balochistan only the Quetta city locale could provide a
figure for the number of male <strong>in</strong>patient hero<strong>in</strong> addicts
treated <strong>in</strong> the past year.

CALCULATION SHEET SUMMARY (2)
The second Calculation Summary Sheet extends the estimates
made <strong>in</strong> Summary Sheet 1 of the numbers of
treated hero<strong>in</strong> addicts to give estimates of the likely range
of total numbers of hero<strong>in</strong> addicts for each localegroup<strong>in</strong>g,
and for <strong>Pakistan</strong> as a whole.
4. Key Informant and Interview Treatment Multipliers
The range of multipliers used to represent the number of addicts not
<strong>in</strong> treatment <strong>in</strong> the year is a composite of all study data
The Key Informant component of the National Assessment
provided <strong>in</strong>formation on the percentage of addicts treated
<strong>in</strong> each of the locale-group<strong>in</strong>gs. Key <strong>in</strong>formants, exclud<strong>in</strong>g
police and treatment-related personnel, who had contact
with at least ten addicts over the previous year reported
on how many of these had received <strong>in</strong>patient treatment
dur<strong>in</strong>g the year.
These reports from all <strong>in</strong>cluded Key Informants <strong>in</strong> the
locale-group<strong>in</strong>gs gave a median figure for the percentage
of addicts receiv<strong>in</strong>g <strong>in</strong>patient treatment over the previous
year. Amongst these reports the 25%-tile (1st quartile) is
used as a m<strong>in</strong>imum likely estimate and the 75%-tile is
used as a maximum likely estimate to provide a likely range
for the estimate of the percentage of addicts who were
treated.
These treatment percentages enable the calculation of a
range of 'treatment multipliers'—factors that give the
required <strong>in</strong>flation factor of local <strong>in</strong>patient treatment
figures to give the total number of local treated and untreated
addicts. These <strong>in</strong>flation multipliers are applicable
to the estimated number of local addicts receiv<strong>in</strong>g <strong>in</strong>patient
treatment for each (of 7) locale-group<strong>in</strong>g.
The Treatment Register Update <strong>in</strong>terviews <strong>in</strong> the cl<strong>in</strong>ics
provided <strong>in</strong>formally data on the percentage of treated
addicts at the listed specialist cl<strong>in</strong>ics who are from the
local catchment areas, and this catchment 'correction
factor' has been taken at 90% <strong>in</strong> the <strong>in</strong>itial estimation
procedures.
Comb<strong>in</strong><strong>in</strong>g, for each of the locale group<strong>in</strong>gs separately,
the figures for the multiplier and the catchment correction
factor with the numbers of <strong>in</strong>patient treated addicts
derived <strong>in</strong> section 3 of the Summary Sheet gives the
estimated total number of hero<strong>in</strong> addicts <strong>in</strong> the study
locales.
