在撒哈拉以南非洲，電力會中斷，低科技很普遍，網路速度慢，醫院人手不足，這些都是健康照護系統得克服的難題。為了改善馬拉威的這些問題，TED 成員索亞皮孟巴和團隊創造了一個新的系統，從無到有－從處理電子健康記錄的軟體，到用來支援軟體的基礎設施。在這場簡明、充滿希望的演說中，孟巴分享了他的萬事通心態如何協助改造低資源環境中的健康照護。

00:23
I read articles on tech blogs

我會閱讀科技部落格上的文章，
00:25
and listen to podcasts on my phone.
4

2120
也會用我的手機聽播客。
00:29
But after I finish the article,
5

1816
但，在我讀完文章，
00:30
lock my phone and unplug the headphones,
6
18920
3336
把我的手機上鎖，並拔掉耳機之後，
00:34
I'm back in sub-Saharan Africa,
7
22280
2216
我就回到了撒哈拉以南非洲，
00:36
where the landscape is not quite the same.
8
24520
2440
在那裡，狀況不太一樣。
00:40
We have long and frequent power outages,
9
28160
2640
我們常常會有很長時間的電力中斷，
00:43
low penetration of computers,
10
31720

電腦的普及率很低，
00:45

and a lot of patients

許多病人得要造訪人手不足的醫院。
00:52
Since the HIV epidemic,

2136
從愛滋病毒的流行開始，
00:54
hospitals have been struggling
to manage regular HIV treatment records

01:21
We designed an electronic

我們設計了一個電子健康記錄系統，

23

01:28
And in the process we realized that we
not only had to design the software,
not only had to design the software,
24
76520

在過程中，我們發現，
我們不僅需要設計軟體，
我們不僅需要設計軟體，
01:33
we had to implement
the infrastructure as well.

25
81120
2360
我們還得導入基礎設施。
01:36
We don't have enough medical staff
26
84640
2216
我們沒有足夠的醫療人員
01:38
to comprehensively examine every patient,
27
86880
2856
來廣泛全面地檢查每一位病人，
01:41
so we embedded clinical guidelines
within the software
within the software
28
89760
3056
所以我們在軟體中建置了臨床指南，
01:44
to guide nurses and clerks
29
92840
2176
用來指導護士和見習醫生，
01:47
who assist with handling
some of the workload.
some of the workload.
30
95040
2160
這樣可以減低工作量。
01:50
Everyone has a birthday,
31
98000
1656
每個人都有生日，
01:51
but not everyone knows their birthday,
32
99680
2496
但不是每個人都知道他們的生日，
01:54
so we wrote algorithms
to handle estimated birthdates
to handle estimated birthdates
33
102200
3816
所以我們寫了演算法來估計生日，
01:58
as complete dates.
34
106040
1280
當作完整日期。
02:00
How do we follow up
patients living in slums

35
108200
3936
貧民窟沒有街道號碼，我們要如何
02:04
with no street and house numbers?
36
112160
2200
追蹤住在那裡的病人？
02:07
We used landmarks to approximate
their physical addresses.

37
115200
3880
我們用地標來當作約略的實體地址。
02:12
Malawi had no IDs
to uniquely identify patients,
to uniquely identify patients,
38
120040
3440
馬拉威並沒有 ID 來明確區別病人，
02:16
so we had to implement unique patient IDs
39
124480
3136
所以我們得要建置不重覆的病人 ID，
02:19
to link patient records across clinics.
40
127640
2240
把各診所的病人記錄連結起來。
02:22
The IDs are printed as barcodes
41
130919
2441
我們把 ID 列印成條碼，
02:26
on labels that are stuck
on personal health booklets
on personal health booklets
42
134200
2856
印在每個病人持有的個人健康手冊上
02:29
kept by each patient.
43
137080
1200
所附的標籤上。
02:31
With this barcoded ID,
44
139000
1976
有了這種條碼 ID，
02:33
a simple scan with a barcode reader
45
141000
2416
加上一個簡單的條碼掃瞄器，
02:35
quickly pulls up the patient's records.
46
143440
2240
就能馬上調閱病人的記錄。
02:38
No need to rewrite their personal details
47
146440
2296
不需要在病人每次造訪時都還得在
02:40
on paper registers at every visit.
48
148760
2416
書面登記資料上重寫其個人細節。
02:43
And suddenly, queues became shorter.
49
151200
2656
突然間，排隊隊伍就變短了。
02:45
This meant patients, typically mothers
with little children on their backs,
with little children on their backs,
50
153880
4896
這意味著，病人，
通常是背著小孩的母親，

02:50
had to spend less time
waiting to be assisted.

51
158800
3136
不用再花那麼長的時間等待協助。
02:53
And if they lose their booklets,
52
161960
1936
如果病人弄丟了自己的手冊，
02:55
their records can still be pulled
by searching with their names.
by searching with their names.
53
163920
3176
還是可以透過搜尋他們的名字
來把記錄調出來。

02:59
Now, the way we pronounce
and spell names varies tremendously.

54
167120

我們的名字有非常不同的
發音和拼音方式，
發音和拼音方式，
03:04
We freely mix R's and L's,

172360

我們可以自由混合 R 和 L，
03:07
English and vernacular
versions of their names.

56
175080
2840
他們的名字還有英語版和方言版。
03:10
Even soundex,
57
178680
1416
即使是 Soundex 演算法，
03:12
a standard method for grouping words
by how similar they sound,

58
180120
4416
它是一種將字詞依發音
相似度來分類的標準方法，

03:16
was not good enough.
59
184560
1576
用在這裡也不夠好。
03:18
So we had to modify it
60
186160
1696
所以我們得要修改它，
03:19
to help us link and match
existing records.
existing records.
61
187880
3800
來協助我們連結和配對既有的記錄。
03:26
Before the iPhone,
62
194160
1200
在 iPhone 推出前，
03:28
software engineers
developed for personal computers,
developed for personal computers,
63
196040
3816
軟體工程師是為個人電腦在做開發，
但，根據我們的經驗，
03:31
but from our experience,
64
199880
1256
03:33
we knew our power system
is not reliable enough
is not reliable enough
65
201160
3376
我們知道，若要用個人電腦，
我們的電力系統不夠可靠。
03:36
for personal computers.
66
204560
1280
03:38
So we repurposed touch screen
point-of-sale terminals
point-of-sale terminals
67
206480
4656
所以我們把觸碰螢幕銷售點
終端機拿來做不同的用途，

03:43
that are meant for retail shops
68
211160
1696
它們本來是給零售店使用的，
03:44
to become clinical workstations.
69
212880
1760
被我們變成了臨床工作站。
03:47
At the time, we imported
internet appliances called i-Openers

70
215920
4160
那時，我們進口了網路家電，
叫做 i-Openers，
叫做 i-Openers，
03:52
that were manufactured
during the dot-com era

71
220960

那是在網路公司時代，由一間失敗的
03:56
by a failed US company.
72
224000
1840
美國公司所製造的。
03:59
We modified their screens
73
227080
2296
我們修改了他們的螢幕，
04:01
to add touch sensors
74
229400
1376
加上觸碰感測器，
04:02
and their power system
to run from rechargeable batteries.

75
230800
3320
還有用可充電電池
來運作的電力系統。

04:06
When we started, we didn't find
a reliable network to transmit data,

76
234680

一開始時，我們找不到
可靠的網路來傳輸資料，
可靠的網路來傳輸資料，
04:11
especially from rural hospitals.
77
239840
1640
特別是在郊區的醫院。
04:14
So we built our own towers,
78
242240
2720
所以，我們建立了我們自己的塔台，
04:17
created a wireless network
79
245720
1896
創建了無線網路，
04:19
and linked clinics in Lilongwe,
80
247640
2416
連結了馬拉威首都里郎威的診所。
04:22
Malawi's capital.

257600
1600
一個工程師團隊
04:32
working within a hospital campus,
84
260200
2296
被安排在醫院園區內工作，
04:34
we observed health care workers
use the system

85
262520
2656
讓我們能觀察健康照護人員
使用系統的狀況，
使用系統的狀況，
04:37
and iteratively
build an information system

86
265200

並反覆地繼續建立資訊系統，
04:40
that is now managing HIV records
87
268440
3816
這個系統現在可管理馬拉威所有
04:44
in all major public hospitals in Malawi.
88
272280

主要公立醫院的愛滋病毒記錄。
04:47
These are hospitals serving
over 2,000 HIV patients, each clinic.

90

健康照護人員過去需要花數天時間
04:57
to tally and prepare quarterly reports
91

2136
記錄和準備季報表，
04:59
are producing the same reports

are now coming to Malawi

97
304960
2816
很鼓舞人心也很有趣，
05:19
but to make them work
98
307800
2096
但要讓它們也能用在
05:21
in low-resourced environments
99
309920
2176
缺乏資源的環境裡，
05:24
like public hospitals
in sub-Saharan Africa,
in sub-Saharan Africa,
100
312120
3176
比如撒哈拉以南非洲的公立醫院，
05:27
we have had to become jacks-of-all-trades
101
315320
3776
我們必須要成為百事通，
05:31
and build whole systems,
including the infrastructure,
including the infrastructure,
102
319120
3536
建立整個系統，包含基礎設施，
